Description

Technical Field

[0001] This application relates to the field of welding technology, specifically to a welding fixture and welding system for T-shaped structures. Background Technology

[0002] During ship design and construction, to ensure the overall strength of the ship, numerous transverse and longitudinal T-shaped structures are welded to the inner sides of the hull structure, including the hull plating and bulkheads. These T-shaped structures are composed of transverse and longitudinal plates. In the ship section manufacturing stage, the transverse and longitudinal plates are first assembled into T-shaped structures, then welded, ground, repaired, and straightened. These T-shaped structures are then assembled onto the hull plating, bulkheads, and other hull structures. Multiple hull plating and bulkhead structures are combined into sections and welded together.

[0003] The original method for welding ship T-structures involved manual welding by welders using handheld gas shielded welding torches. This method resulted in poor welding quality, low welding efficiency, and required multiple re-welding and grinding processes to meet quality requirements. Furthermore, the fumes and high temperatures generated during the welding process had a significant impact on the health of welding workers.

[0004] In recent years, welding methods for ship T-structures have been gradually innovated, with welding carriages replacing manual welding, effectively ensuring welding quality and reducing the workload of post-weld grinding and repair welding. However, the welding heat input of longer T-structures is relatively large, and welding deformations such as longitudinal bending, lateral bending, and twisting will occur during the welding process. This causes the welding carriage to deviate from the weld, thus affecting the welding quality. Post-weld, a significant amount of time is required for fire correction, which is quite difficult.

[0005] Therefore, it is necessary to manufacture a longer T-shaped welding trolley auxiliary tooling to improve the welding quality of the T-shaped structure and effectively control welding deformation during the welding process. Summary of the Invention

[0006] This application provides a welding fixture and welding system for T-shaped structures, which addresses the technical problem of welding deformations such as longitudinal bending, lateral bending, and torsion that occur during the welding process of long T-shaped structures, causing the welding carriage to deviate from the weld and thus affecting the welding quality.

[0007] In a first aspect, embodiments of this application provide a welding fixture for a T-shaped structure, the welding fixture comprising: a base and a fixing assembly. The top surface of the base has the T-shaped structure placed upside down, and the top surface of the base contacts the transverse plate of the T-shaped structure; the fixing assembly includes several limiting members and several locking blocks, the limiting members being arranged in a row on the base, with a gap between the limiting members and the top surface of the base, one transverse plate of the T-shaped structure being located within the gaps between all the limiting members, and each locking block being inserted into the gap and abutting against the top surface of each limiting member and the transverse plate.

[0008] In conjunction with the first aspect, in one embodiment, the limiting member is an inverted L-shape, with the vertical ends of several limiting members evenly fixed to the side of the base, and their horizontal ends parallel to the top surface of the base, with the intervals between them.

[0009] In conjunction with the first aspect, in one embodiment, the card block includes a head and a tail, with an inclined surface between them, and the thickness of the head is less than the thickness of the tail.

[0010] In conjunction with the first aspect, in one embodiment, the tail of the card block has a protrusion in the thickness direction, and the protrusion is located on one side with an inclined surface.

[0011] In conjunction with the first aspect, in one embodiment, the bottom surface of the base is evenly provided with a plurality of support legs for supporting the base.

[0012] Secondly, embodiments of this application provide a welding system for a T-shaped structure. The welding system includes: welding fixtures for a T-shaped structure as described in any of the above embodiments; the welding system also includes a welding trolley placed on the top surface of the base, a guide device fixed to one side of the welding trolley facing the T-shaped structure, and the movement trajectory of the guide device extends along the longitudinal plate of the T-shaped structure, and the movement trajectory is parallel to the top surface of the base.

[0013] In conjunction with the second aspect, in one embodiment, the guiding device includes a first guide rod and a second guide rod, one end of each guide rod being fixedly connected to the welding trolley, and the other end of the guide rod being provided with a guide wheel and slidably disposed with the longitudinal plate of the T-shaped structure.

[0014] In conjunction with the second aspect, in one embodiment, the length of the first guide rod is less than the length of the second guide rod, and the first guide rod is oriented towards the front of the welding trolley displacement.

[0015] In conjunction with the second aspect, in one embodiment, the ends of the first guide rod and the second guide rod are provided with grooves, the central shaft of the guide wheel is installed on the inner wall of the groove, and the guide wheel protrudes from the outside of the groove.

[0016] In conjunction with the second aspect, in one embodiment, both the first guide rod and the second guide rod have L-shaped mounting plates at their ends where the guide wheels are mounted. The vertical plate of the L-shaped mounting plate is fixedly connected to the end, and the top surface of its horizontal plate is connected to the central axis of the guide wheel.

[0017] The beneficial effects of the technical solutions provided in this application include:

[0018] In this application, by inserting one side transverse plate of the T-shaped structure into the gap between several limiting members and the top surface of the base, and using several locking blocks to hold each limiting member and the top surface of the transverse plate, a force opposite to the direction of lateral and longitudinal bending deformation can be generated to control the deformation. This solves the technical problem in the prior art where welding deformations such as longitudinal bending, lateral bending, and twisting occur during the welding process of long T-shaped structures, causing the welding carriage to deviate from the weld and thus affecting the welding quality.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0030] This application provides a welding fixture and welding system for T-shaped structures, which can solve the technical problem that welding deformations such as longitudinal bending, lateral bending and twisting occur during the welding process of long T-shaped structures, causing the welding carriage to deviate from the weld and thus affecting the welding quality.

[0031] In a first aspect, embodiments of this application provide a welding fixture for a T-shaped structure 3.

[0032] In one embodiment, reference is made to Figure 1 This is a schematic diagram illustrating the cooperation between the welding fixture and the welding carriage used in the T-shaped structure 3 in this embodiment of the application. Figure 1 As shown, the welding fixture for the T-shaped structure 3 includes a base 1 and a fixing component 2. The base 1 is used to support the T-shaped structure 3, and the fixing component 2 is used to fix the T-shaped structure 3. By setting the fixing component 2 on the base 1, welding deformations such as longitudinal bending, lateral bending and twisting can be effectively prevented from occurring during the welding process of the T-shaped structure 3.

[0033] Preferred, refer to Figure 2 ,for Figure 1 Left view of the welding fixture used for the T-shaped structure. (See image below.) Figure 2 As shown, the T-shaped structure 3 is placed upside down on the top surface of the base 1. When the T-shaped structure 3 is in the upside-down state, the top surface of the base 1 is in contact with the horizontal plate 31 of the T-shaped structure 3. In this embodiment, the base 1 is rectangular and has a certain length, which can completely accommodate the relatively long T-shaped structure 3. The T-shaped structure 3 also includes a vertical plate 32, which is perpendicular to the horizontal plate 31. It should be noted that before welding the T-shaped structure 3, the material cutting department will cut a large steel plate into many pieces of the dimensions specified in the drawings, that is, cut the large steel plate into horizontal plates 31 and vertical plates 32 according to the dimensions in the drawings. Then the assembler will assemble the horizontal plates 31 and vertical plates 32 into a T-shaped structure and fix it by local spot welding. Thus, the T-shaped structure 3 required in this application is formed.

[0034] like Figure 2As shown, the fixing device includes several limiting members 21 and several locking blocks 22. The limiting members 21 are arranged in a row on the base 1, and a gap 23 is left between the limiting members 21 and the top surface of the base 1. The transverse plate 31 on one side of the T-shaped structure 3 is located within the gap 23 of all the limiting members 21. Each locking block 22 is inserted into the gap 23 and abuts against the top surface of each limiting member 21 and the transverse plate 31. In this embodiment, the T-shaped structure 3 is welded on the base 1. At this time, the base 1 is equivalent to a "workbench". Placing the T-shaped structure 3 on the base 1 for welding not only helps the welding work to proceed smoothly, but also prevents dust, impurities, etc. on the bottom surface from soiling the T-shaped structure 3. In addition, the base 1 can have a certain height, which is more conducive to the welding operation of the T-shaped structure 3, and can even weld other irregular structures, making it highly applicable. The base 1 has a certain length, and a number of limiting members 21 are arranged in a row on the base 1. Preferably, the number of limiting members 21 are evenly arranged in a row along the length direction of the base 1.

[0035] Because the longer the T-shaped structure 3 is during welding, the greater its deflection and the easier it is to deform. Furthermore, its longitudinal bending deformation is upward at both ends, and its lateral bending deformation is inclined towards the welding side. Therefore, by arranging several limiting members 21 in a row on the base 1, with a gap 23 between the limiting members 21 and the top surface of the base 1, and with one side transverse plate 31 of the T-shaped structure 3 located within the gap 23 of all the limiting members 21, and inserting each locking block 22 into the gap 23 and abutting against the top surface of each limiting member 21 and the transverse plate 31, a force opposite to the lateral and longitudinal bending deformation directions is formed to control the deformation. This solves the technical problem in the prior art where welding deformations such as longitudinal bending, lateral bending, and twisting occur during the welding process of long T-shaped structures 3, causing the welding carriage 4 to deviate from the weld and thus affecting the welding quality.

[0036] Furthermore, in one embodiment, such as Figure 1 As shown, the limiting member 21 is an inverted L-shape, with the vertical ends of several limiting members 21 evenly fixed to the side of the base 1, and their horizontal ends parallel to the top surface of the base 1, with a gap 23 between them. In this embodiment, by setting the limiting member 21 to an inverted L-shape, and with the vertical ends of several limiting members 21 evenly fixed to the side of the base 1, and their horizontal ends parallel to the top surface of the base 1, with a gap 23 between them, it is beneficial for the horizontal plate 31 on one side of the T-shaped structure 3 to be placed in the gap 23 between the limiting member 21 and the top surface of the base 1, making the operation simple, time-saving, and labor-saving.

[0037] Preferred, such as Figure 2As shown, several limiting members 21 are uniformly fixed on the side of the base 1, and the horizontal end faces of all limiting members 21 are in a straight line in space, and the height of the horizontal ends of all limiting members 21 is at the same height. This can enhance the stability of the structure and avoid uneven stress on each section during the welding of the T-shaped structure 3, or even some places not being fixed in place, which could cause local deformation.

[0038] Furthermore, in one embodiment, reference is made to Figure 3 This is an enlarged schematic diagram of card block 22 in an embodiment of this application. Figure 3 As shown, the locking block 22 includes a head 221 and a tail 222, with an inclined surface 223 between them, and the thickness of the head 221 is less than the thickness of the tail 222. In this embodiment, since the thickness of the head 221 of the locking block 22 is less than the thickness of the tail 222, the locking block 22 can be inserted into the designated position more easily. Furthermore, since there is an inclined surface 223 between the head 221 and the tail 222, once the head 221 of the locking block 22 enters the designated position, the fixing effect of the tail 222 increases with the increase of the insertion depth, which can effectively prevent the locked object (i.e., one side of the T-shaped structure 3) from coming out and loosening, thereby causing the welding carriage 4 to deviate from the weld and thus affecting the welding quality.

[0039] Furthermore, in one embodiment, such as Figure 3 As shown, the tail 222 of the locking block 22 has a protrusion 224 in the thickness direction, and the protrusion 224 is located on the side with the inclined surface 223. In this embodiment, by providing a protrusion 224 in the thickness direction of the tail 222 of the locking block 22, and the protrusion 224 being located on the side with the inclined surface 223, after the T-shaped structure 3 is welded and cooled, the worker can use a hammer to strike the protrusion 224, thereby quickly releasing the locking block 22, making disassembly extremely convenient and improving work efficiency.

[0040] Furthermore, in one embodiment, such as Figure 1-2 As shown, the bottom surface of the base 1 is evenly provided with a plurality of support legs 11. In this embodiment, by evenly providing a plurality of support legs 11 on the bottom surface of the base 1, the base 1 can be made to have a certain height from the ground, so as to avoid dust and debris on the ground from contaminating the T-shaped structure 3 when welding the T-shaped structure 3. At the same time, it can also be adapted to welding irregular structures, and the ends of the irregular structures can be placed at the ends of the base 1 for fixing and welding.

[0041] Preferably, in other embodiments, the bottom surface of the support leg 11 may also be provided with a rubber pad or a leveling component. In this way, even on uneven ground, the welding fixture can be used normally by means of the rubber pad or leveling component, and its environmental adaptability is extremely strong.

[0042] Secondly, embodiments of this application also provide a welding system for a T-shaped structure 3.

[0043] In one embodiment, such as Figure 1 As shown, the welding system includes: a welding fixture for the T-shaped structure 3 as in any of the above embodiments and a welding trolley 4 that cooperates with the welding fixture to perform welding. The two work together to achieve uniform welding speed compared to manual welding. In addition, it can also ensure that the weld corner size error is small.

[0044] For preferred options, please refer to [the provided text]. Figure 1 and Figure 4 , Figure 4 This is a top view showing the cooperation between the welding fixture and the welding carriage 4 used for the T-shaped structure 3 in an embodiment of this application. Figure 1 and Figure 4 As shown, the welding carriage 4 is placed on the top surface of the base 1. A guide device 41 facing the T-shaped structure 3 is fixed to one side of the welding carriage 4, and the movement trajectory of the guide device 41 extends along the longitudinal plate 32 of the T-shaped structure 3, and the movement trajectory is parallel to the top surface of the base 1. In this embodiment, placing the welding carriage 4 on the top surface of the base 1 means that the welding carriage 4 moves on the top surface of the base 1 when welding the T-shaped structure 3. In addition, in order to ensure that the welding rod of the welding carriage 4 does not deviate from the weld, the guide device 41 facing the T-shaped structure 3 can be fixed to one side of the welding carriage 4. By making the movement trajectory of the guide device 41 extend along the longitudinal plate 32 of the T-shaped structure 3 and the movement trajectory parallel to the top surface of the base 1, it can be ensured that the movement trajectory of the welding carriage 4 is consistent with the movement trajectory of the guide device 41, so that the welding rod of the welding carriage 4 does not deviate from the weld, thereby ensuring the welding quality.

[0045] Furthermore, in some embodiments, such as Figure 4As shown, the guiding device 41 includes a first guide rod 411 and a second guide rod 412. One end of each guide rod is fixedly connected to the welding carriage 4, and the other end of the guide rod is provided with a guide wheel 413, which is slidably disposed with respect to the longitudinal plate 32 of the T-shaped structure 3. In this embodiment, the guiding device 41 and the welding carriage 4 can be threaded together for easy disassembly and installation. By fixing one end of the two guide rods (i.e., the first guide rod 411 and the second guide rod 412) to the welding carriage 4, and providing a guide wheel 413 at the other end of the guide rod, which is slidably disposed with respect to the longitudinal plate 32 of the T-shaped structure 3, the welding carriage 4 maintains a certain distance from the longitudinal plate 32 of the T-shaped structure 3 during welding operations. Under the guidance of the guiding device 41, the welding rod of the welding carriage 4 is ensured not to detach from the weld seam, thus smoothly completing the welding operation on the T-shaped structure 3. Furthermore, the use of the guide wheel 413 sliding on the longitudinal plate 32 of the T-shaped structure 3 reduces the frictional resistance during the movement of the guide rod, preventing the welding carriage 4 from being accidentally jammed during welding and ensuring smoother movement.

[0046] Furthermore, in one embodiment, such as Figure 4 As shown, the length of the first guide rod 411 is less than the length of the second guide rod 412, and the first guide rod 411 is oriented towards the front of the welding carriage 4. In this embodiment, the length of the first guide rod 411 is less than the length of the second guide rod 412, forming a certain length difference, and causing the first guide rod 411 to be oriented towards the front of the welding carriage 4. In this way, when the welding carriage 4 is welding, it will tilt slightly towards the longitudinal plate 32 of the T-shaped structure 3, which is more conducive to ensuring that the welding rod of the welding carriage 4 does not detach from the weld, and successfully completes the welding operation of the T-shaped structure 3.

[0047] Furthermore, in one embodiment, such as Figure 4 As shown, the ends of the first guide rod 411 and the second guide rod 412 are provided with grooves, and the central axis of the guide wheel 413 is installed on the inner wall of the groove, with the guide wheel 413 protruding from the outside of the groove. In this embodiment, as can be seen from the above embodiments, the ends of both guide rods are provided with guide wheels 413, which not only ensures that the welding carriage 4 maintains a certain distance from the longitudinal plate 32 of the T-shaped structure 3, preventing the welding rod of the welding carriage 4 from deviating from the weld seam, but also reduces the frictional resistance when the guide rods move, so that the welding carriage 4 will not be accidentally stuck during welding, and the movement is smoother.

[0048] In this embodiment, there are several ways to install the guide wheel 413. One method is direct installation, where grooves are provided at the ends of the first guide rod 411 and the second guide rod 412. The central axis of the guide wheel 413 is installed on the inner wall of the groove, and the guide wheel 413 protrudes outside the groove. This ensures that the guide wheel 413 will not shift or wobble due to uneven force during sliding, thus enhancing stability. Furthermore, the fit between the groove and the central axis of the guide wheel 413 ensures the positional accuracy of the guide wheel 413, which helps reduce wear and deviation caused by improper installation or long-term use.

[0049] Furthermore, in one embodiment, such as Figure 4 As shown, both the first guide rod 411 and the second guide rod 412 have L-shaped mounting plates 414 at their ends where the guide wheel 413 is mounted. The vertical plate of the L-shaped mounting plate 414 is fixedly connected to the end, and the top surface of its horizontal plate is connected to the central axis of the guide wheel 413. In this embodiment, there are multiple ways to install the guide wheel 413. An indirect installation method is adopted, that is, by providing L-shaped mounting plates 414 at the ends of the first guide rod 411 and the second guide rod 412 where the guide wheel 413 is mounted, the vertical plate of the L-shaped mounting plate 414 is fixedly connected to the end, and the top surface of its horizontal plate is connected to the central axis of the guide wheel 413. This increases the stability of the connection between the guide rod and the guide wheel 413. The fixed connection between the vertical plate and the end of the guide rod provides a strong supporting force, while the horizontal plate effectively fixes the central axis of the guide wheel 413 to it, thereby forming a stable triangular structure and enhancing the torsional and compressive resistance of the entire system. Installing the guide wheel 413 in this way also facilitates disassembly and reinstallation if the guide wheel 413 needs to be replaced or repaired, reducing maintenance costs. It should be noted that the L-shaped mounting plate 414 can be integrally molded or pre-welded.

[0050] In some other embodiments, a strong magnet is fixed to the bottom surface of the welding carriage 4, and the base 1 is generally made of steel. The welding carriage 4 is placed on the base 1, and the magnet can attract the base 1, so that the welding carriage 4 is stably placed on the base 1.
